No hydroelectric uses water, usually stored behind a dam to drive a turbine. The hot rocks you speak of is geothermal energy. The most prolific use of geothermal energy is in Iceland.
the difference between the hydroelectric energy and the hydrothermal is hydrothermal is using geothermal heat (hot rocks) to create electricity by pumping it while the hydroelectric energy it uses the high dams and waterfall to create electricity.
Idaho. 78% of their power comes from hydroelectric sources.
China uses the most Hydroelectric power in the world
60%
about 20%.
Hydroelectric power plants. They have dams and generators. Water flows through a dam, which spins generators that produce hydroelectric electricity. (Fun Fact: The Hoover Dam is the biggest hydroelectric power plant.)
there are no bad uses of hydro electricity and cant be
we use the most hydroelectric power in kansas
A hydroelectric dam uses the force of flowing water to drive turbines which generate electric power.
Hydroelectric power
Both use the flow of water generate electricity. Hydroelectric uses the flow of water from a high point to a low point. (A damn). Tidal power uses the flow of ocean tides in and out.
Hydroelectric energy uses water. Thermal energy uses heat. Simple Science! Duh!
